When performing linear regression from EG, our data scientists always want to save the parameter estimates to a data set for use
in subsequent tasks.
in the current versions of EG they have to manually insert code to add outest= option.
after running the task with inserted code, the outest data set does not appear on project canvas, the user has to select it manually
from server list and add it to the project canvas and connect it to the regression task.
idea: add an option to the linear regression task to save parameter estimates to a data set (generate code: outest=<data-set-name>) and
add that data set to the project canvas.
